SCA: security update for gettext-converter (GHSA-f4jp-rw7w-ccwg)

high Tenable Self-Hosted Container Security Plugin ID 446192

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - gettext-converter provides gettext resource conversion utilities for JavaScript. Prior to 1.3.3,
 js2i18next() in lib/js2i18next.js splits nested translation keys using options.keyseparator, whose default
 value consists of two number signs, and uses each segment as a dynamic object key without rejecting
 __proto__, constructor, or prototype. When an application converts untrusted PO or i18next translation
 data, a __proto__ segment resolves Object.prototype as the nested write target and Object.assign writes
 attacker-controlled translated properties onto the process-wide prototype. The resulting prototype
 pollution can cause denial of service and may enable application-dependent follow-on attacks. This issue
 is fixed in version 1.3.3. (CVE-2026-55451)

Solution

Update the gettext-converter library and its related packages to version 1.3.3 or later.
